What's wrong with my fish?

[Oilers]

I've had this scott fairy wrasse for a couple months now. Last night, when I was feeding the fishes, I noticed that one of his eyes is not normal. It looks bulgy and glassy. He was fine all along. Can you tell me what that is or what's causing it? Is that normal? Is it contagious? How do I cure him? Thanks.

Sorry for the crappy phone pic. I took it this morning when the light is out.
